Right!
I took the thing apart this evening, just to see what I could find and to see why some of the reeds weren't working. It turns out it was just some crud stuck in them. Cleaned them out, and got them al working bar the buzzing F. The reed is touching the plate, I tried very delicately jiggling it around with a small magnetic screwdriver, but couldn't get it into the right position. Any tips?
It turns out the blank and half-blank buttons in my diagrams are:
right hand accidentals row: the blank one is Bb/Db, the one to its left is G/E
Left hand accidentals row: the leftmost button is F#/Eb
Left hand middle row: the leftmost button is Bb/F
Left hand lower row: the leftmost button is A/C
Also, some of the leather valves are missing. I should have some suitably thin leather, so I might replace them.
Another thing that I found is what appears to be a serial number, 17860, stamped on the bottom of both of the wooden plate the action is attached to (sorry for the highly technical language).
Next thing is to is glue the pad of the right hand side Bb/Db button back as it has come unstuck from the end of the lever. Do you reckon hide glue would be ok? As a trainee violin-maker I have plenty of the stuff around, and I'd rather use something reversible and possibly historically accurate rather than synthetic glue.

Thank you!
The dates and area George Jones was active certainly match up with what I had supposed.
As for the hand straps, as far as I can tell they are simply held with one screw in the side frame and one in the end of the wooden hand rest, so I should be able to simply unscrew them and replace them. They will definitely be preserved!
If it's of interest, I've attached the note layout, hope it is legible. As you can tell, I was wrong in my original post, it is in fact a Bb/F. The blank buttons are the ones that don't make any sound. The only reeds which seem seriously out of tune are the F on the pull of the last button of the F row on the right hand and the C on the pull of the first button on the bottom row of the left hand. The F buzzes, so I hope it's just a matter of cleaning.
This is more of a repair and restoration question, but should I grease the bellows at all? They seem a bit stiff, and I wouldn't want to damage them. I am a bit concerned about weakening the glue.

Thanks Pgidley!
Barring the two buttons that don't appear to work, there aren't any novelty noies. The right hand picture in the catalogue appears to be a fairly similar instrument to mine, although, as you say, the descriptions don't quite match up.
My concertina has bone rather than metal buttons, but the fact that the maker's label appears to be missing might mean that it has had some work done to it.
I haven't got it with me at the moment, but I'll post the note layout as soon as I can.
The bellows are in good shape. As far as I can tell there are no significant leaks.

Greetings,
A few years ago I was given this 34 button C/G anglo. It came with what looks to me like its original wooden box, minus the carrying handle and key.
The instrument belonged to my great-great grandfather, who lived in east London sometime in the second half of the XIXth century.
As you can see from the photos, instrument is in pretty good nick, considering no-one must have played it for many decades. It is pretty much in tune, although a couple of reeds buzz and the two buttons at the treble end of the right-hand side accidentals row don't produce any sound. Apart from that, the straps need replacing as the leather is very nearly worn through where they go through the brass loop at the end of the hand rest.
As far as the layout goes, I haven't been able to find a layout that matches exactly. One feature that I have heard is a bit unusual is a low C drone button on the left hand
I haven't opened the instrument yet, although I will once I have mustered up the courage. There are no markings of any kind that I can see on the outside, the metal facing on the right hand end has an oval window, but unlike other concertinas I have seen, there is no label in it.
Does anybody know who the manufacturer could be?
